MANUAL SHIFT FOR MOLD-Dll SLIDES.

Specification of Letters Patent.

Patented Nov. 23, 1915.

Application filed April 24, 1914. Serial No. 834,202.

To all whom t may concern:

Be it known that l, HENRY A. ARMSTRONG, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Manual Shifts for Mold- Disk Slides, of which the following is a specification.

My present invention relates to improvements in typographical machines and more especially to those of the linotype class employing a mold disk and a metal pot cooperative therewith to inject metal into a mold on the mold disk, the mold disk being mounted on a slide which is reciprocated at appropriate intervals `by power derived from a cam.

The primary object of the invention is to provide novel means for disconnecting the mold disk slide from its power-actuating means and moving the slide forward away from its normal operative position for the purpose of cleaning the mouthpiece of the metal pot or for removing any metal which may have dropped from the mouthpiece of the metal pot to the back of the mold disk, the construction provided by the present invention enabling the slide to be brought forward by a single operation and without requiring the operator to handle the mold disk, and the mold disk being returned to operative position by a single movement.

To this end, the invention consists in certain improvements, and combinations and arrangements of parts, all as will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification.

In the accompanying drawing the ligure is a side elevation of a mold disk and slide provided with the operating means for the latter as commonly used on machines of the linotype class, the same having the present invention applied thereto. Y

In the present instance 1 represents column forming part of the main frame of the machine and 2 designates a bracket which is rigidly bolted or otherwise secured to the column and supports the pump-actuating spring 3 and the shaft 4;, a link 5 being mounted to rock on the shaft 4 and the link being pivotally connected to the upper end of a cam lever 6. The cam lever has a cooperating with a cam 8 which, during its rotation, shifts the moldcarrying slide 10 forwardly and rearwardly. T he roller 9 is normally connected operatively to the mold slide 10 by virtue of its engagement in a notch formed to receive it at the rear end of the slide, an upwardly inclined surface 10iL leading from the rear end of the slide to the recess or notch for the purpose of guiding the roller 9 into the notch when the slide is returned to operative position. rlhe slide l0 carries a bearing 10b, the latter supporting a shaft on which the mold disk or `wheel 11 is mounted, this mold disk or wheel carrying a suitable number of molds 12. These molds are of the usual construction and serve to cast lines of type from assembled lines of matrices and spacers which are `presented in the well known way to the forward side of the mold. The metal is pumped into the rear side of the mold" from a metal pot which has a mouthpiece which extends usually into a recess formed in the rear side of the mold disk, the mouthpiece engaging the rear side of the mold.

Experience has shown that it becomes necessary frequently to clean the mouthpiece of the metal pot by wiping off any metal which may have adhered to its face and such an operation has been inconvenient owing to the fact that the mold disk 11 overhangs the mouthpiece of the metal pot when the parts are in their normal position, rendering it necessary to disconnect the mold slide from its power-actuating means and to draw the mold disk and slide forward by hand in order to give access to the mouth of the metal pot.

The present invention provides means whereby the mold slide and disk can be quickly and easily disconnected from its power-actuating means and drawn forward toA a position where it will be free from the mouthpiece and may be with equal facility returned to operative position. ln the construction shown, a hand lever 13 is provided which is pivoted by the stud 14C to the bracket 2, the lower end of the lever having a pin 15 which operates in a slot formed in the rear end of a link 16, and the forward end of the link 16 is operatively connected to the mold disk slide 10 by a pin 17 on the slide which engages in a notch in the link. A pin 18 is also provided at the lower end of the lever 13 and this pin is adapted to cooperate with a cam 18 formed on the forward end of a lever 19. This lever 19 is pivoted at 20 on the mold disk slide and its rear end is forked to receive a pin or projection 21 on thecam lever 6. A tension spring 22 acts to hold the rear end of the lever 19 in its lower position and against a limiting stop 23 formed on the mold disk slide. When it is desired to move the mold diskA slide forward by hand, the handle or upper end of the lever 13 is pushed rearwardly, causing the pin 18 on the lower end of the lever to ride upon the rear inclined face of the cam 18a, thereby depressing the forward end of this lever 19, as shown by the dotted lines, and raising the rear end of the lever 19 and with it the cam lever 6, the roller 9 on the cam lever being thereby liftedout of its notch in the rear end of the mold disk slide. During this movement of the lever 13 to disconnect the mold disk slide from its poweractuating means, the pin 15 on the lever 13 is moving idly in the slot of the link 16. However, after vthe parts mentioned have been disconnected, the pin 15 reaches the end of the slot in this link 16 and further movement of the lever 13 in the same direction will operate upon the link 16 to shift the mold disk slide forward as far as desired. This further movement of the lever 13 causes the pin 18 to ride down the forward inclined face of the cam 18a, thus allowing the cam lever 6 to descend. By reversing the position of the lever 13, that is to say,

Vby pullingforward upon its upper end, the

mold disk slide is drawn rearwardly and thus returned to normal operative position by the tension on the link 16, the roller 9 riding up' the inclined face 10a at the rear end of the mold slide and then dropping into the notch in which position it will operate the mold disk slide during rotation of the power-actuated cam 8. In each instance a Vvsingle movement of the lever 13 serves to carry the moldv disk slide either to or from operative position according to the direction of movement of the lever, this same lever serving automatically to disconnect or connect the mold disk' slide relatively to its power-actuating means as may be required.

I claim as myinvention 1. The combination with a mold disk slide, and power means for operating it,

of means for manually disconnecting the slide relatively to its power means and for shifting the slide to an inoperative position.

2. The combination with a mold disk slide, and power means for reciprocating it, of means operative manually to bring the mold disk slide into an inoperative position.

3. The combination with a mold disk slide, and power means for reciprocating it, of means operative with a single movement to disconnect said slide from its power means and to shift the slide out of its normal operative position.

4. The combination with a mold disk slide, and power means for reciprocating it, of means operative with a single movement to disconnect said slide from its power means and to shift the slide out of its normal operative position and also operative with a single movement to return the slide to normal position and connect it to its power means.

5. The combination with a mold disk slide, and power means for operating it, of means operative manually to iirst disconnect the slide from its power means and subsequently to move the slide away from its operative position.

6. The combination with a mold disk slide, and power means for operating it, of a device for disconnecting the slide relatively to its power means, a device for shifting the slide out of its normal operative position, and a member common to both of said devices for actuating them successively.

7. The combination with a mold disk slide, a cam, and a cam lever detachably connected to said slide and coperative with the cani for reciprocating the slide,of a device for disconnecting said cam lever from the slide, and a hand lever having means for connecting it'to said slide and operative on said device to disconnect the cam lever from the slide and operative by a further movement to move the slide out of operative position.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

HENRY A. ARMSTRONG. Witnesses:

THOMAS S. HoMANs, W. S. SGUDDER.
